SORT (Statistics and Operations Research Transactions) —formerly Qüestiió— is an international journal launched in 2003. It is published twice-yearly, in English, by the Statistical Institute of Catalonia (Idescat). The journal is co-sponsored by the Universitat Politècnica de Catalunya, Universitat de Barcelona, Universitat Autonòma de Barcelona and Universitat de Girona and with the co-operation of the Spanish Section of the International Biometric Society. SORT promotes the publication of original articles of a methodological or applied nature on statistics, operations research, official statistics and biometrics as well as book reviews.
SORT is indexed in the "Science Citation Index Expanded" (Thomson Scientific) and described in the "Encyclopedia of Statistical Sciences". The journal is also referenced in the "Current Index to Statistics", the "Índice Español de Ciencia y Tecnología", "Statistical Methods and Abstracts", and MathSci of the American Mathematical Society ("Current Mathematical Publications and Mathematical Reviews"). SORT represents the third series of the Quaderns d'Estadística i Investigació Operativa (Qüestiió), published by Idescat between 1992 and 2002, which in turn followed from the first series "Quaderns d'Estadística, Sistemas, Informàtica i Investigació Operativa" (1977-1992). The three series of Qüestiió have their origin in the "Cuadernos de Estadística Aplicada e Investigación Operativa", published by the Universitat Politècnica de Catalunya until 1977.

For any journal to have an Impact Factor, it must be tracked by Thomson Reuters (ISI) for three years. SORT was indexed in the "Science Citation Index Expanded" (Thomson Scientific) beginning with volume 31 (1) 2007. It will have an official Impact Factor in 2009, which is expected to be released in June 2010.
At present, the unofficial 2009 Impact Factor for SORT is 0.33. It is established by dividing the number of times articles published in 2007 and 2008 were cited in 2009, based on a search of the Science Citation Index database, by the number of articles published in the previous two years (2007 and 2008).
